GLUING APPARATUS.

. Patented July 23, 1912.

Application filed December 27, 1910. Serial No. 599,382.

To all whom it may concern:

Be it known that I, LYNooN C. PALMER, a citizen of the United States, residing at Buffalo, in the countyof Erie and State of New York, haveinvcnted certain new and useful Improvements in Gluing Apparatus, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appeitains to make and use the same.

lhis invention has relation to gluing apparatus, and more especially to apparatus of such character which is used in applying glue to webs or strips of paper or similar material employed in the manufacture of paper boxes.

One'object of the invention is the proapparatus for heating the glue.

Another ob ect is the production of a practical apparatus wherewith a series or plurality of paper strips may be glued, thus facilitating rapid operation.

Another objectis the provision of an efficient apparatus for heating a number of lue reservoirs Other objects will be in part obvious and in partpointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings in which similar reference characters refer to similar parts throughoutthe several views, Figure 1 is a plan view of the apparatus; Fig. 2 is an enlarged sectional view on line Ii-wot Fig. 1; and Fig. 3 is an enlarged side view, partly in sectioiif" In the manufacture of boxes, and espe- -cially in the operation of covering boxes.

with paper, a strip of the paper is placed around the sides of the box and attached thereto by glue or pther suitable adhesive.

By this invention the paper is held in position to be readily manipulated and also contiguous to a gluing device, so glue is applied to the paper as the paper is used in the covering operation; and a unitary system of heating the glue is provided for a series or plurality of gluingdehorizontal or body from a single source of heat that the.

vices whereby economy of heat, uniformity of glue, and saving of time are effected, besides other advantages which Will be ap-, parent from the detailed description.

Referringnow in detail to the drawings, the numeral 1 indicates a table or horizontal support, on which is located the gluing apparatus, which comprises a series of heating devices or horizontal plates 2, spaced apart as desired. Each plate is preferably elevated above-the table surface by legs 3 and supports a removable glue reservoir or tank 4;, which rests thereon and is held from lateral displacement by lugs 5 on said plate, between which lugs the tank rests. Each supporting plate 2 has a preferably solid portion and an intermediate depending chambered or channeled portion 5 providing a passageway 7 The passageways in theplates are joined or connected by horizontal pipes 8 removably secured in place, and to one end plate of the series of plates is connected a pipe 9 havinga hand operated out off valve 10. From the other end plate of the series leads a pipe 11 having also a cut off valve 12. By means of this construction the passageways in the several plates are connected in series by the pipes 8 and a suitable medium, preferably steam, boiler, is circulated through the passage: ways in the pipes to furnish heat for the glue.

The glue reservoirs or tanks 4: rest on the surface of the plates 2, respectively, and the plates serve as heaters to melt or soften the glue; Glue feeding rollers 13 dip into the glue in the tanks, respectively, and are preferably journaled on brackets 14: on the side walls of the tank. I Opposite one end of each tank is located a web supporting roller 15 preferably jour naled in brackets 16 secured to the underside of each plate and on the other side a guiding and tension device comprising two rollers 18 and 19.

" hese rollers are so disposed that when the web is passed thercaround in the manner intended and over the glue roller, it. will be drawn over and in cont-act with the glue 2, and curved upwardly to i properly position and accommodate a rollroller as the web is drawn from the supply on the roller 15. Preferably the rollers 17 and 18 are mounted in brackets on the side 'alls of the tank and the roller 19 is mountcd between arms 20 pivoted concentrically to the roller 18 and adjustable around the roller 19, being adapted to be secured in adjusted position by nuts 21. The Web is led from the supply roll beneath the guide roller 17, over the glue roller 13 and between the rollers 18 and 19, thence to the point of use. As the web is drawn oil in use it is drawn across and in contact with the glue roller and glue is applied thereto, and as the glued Web passes between the rollers 18 and l9 'an amount of glue is wiped oil, depending upon the position of the roller 19. Furthermore, the bight of the Web Where it engages the rollers 18 and 19 tends to tension it more ".'or less, thus permitting the outer end 22 of the Web to be cut oil and left hanging Without danger of unthreadiig from the gluing apparatus.

The pipes 8, between the glue tanks, are screened so as to prevent accidental contact therewith by removable covers or hoods 23 comprising substantially semi-circular alls having supporting flanges 9A- resting on the table 1.

By the above described construction the glue reservoirs may be heated from a single source, thus economizing material and labor; individual glue tanks may be readily removed and replaced without interfering with the operation of others, thus facilitating refilling and repair, and the combination as a whole provides a gluing apparatus capable of indefinite extension, and at the same time one that is eminently clean and tree from objectionable features usually present in apparatus working with glue, an especially desirable result when Working with paper and on articles the appearance of which is of material cmisidcratiou.

As many changes could be made in the above cmistruction and many apparently widely dill'erent embodiments of this invention could he made without departing' from the scope thereof, it is intended that all matter contained in the abore description or shown in the acc mmanyi11;: drawings shall. be interpreted as illustrative and not in a lim ting sense. it is also to be under-' stood that thc language used in the followine claims is intended to cover all. of the generic and specific features of the invention herein described and all sialmnents oi? the scope of the invention; which, as a n1at- [or ol'l;|n;r1i;|; "rmight bosaid, to fall. thorobetwccn.
